[Lustre-discuss] stripe don't work

[Alfonso Pardo]

Hello! I just migrate my lustre filesystem to version 2.2. I am trying to activate the stripe, but when I copy a file into the filesystem, it's allocated into only one OST. This is my procedure: From client:  #> lfs setstripe -s 1M /mnt/data/ #> lfs df UUID                   1K-blocks        Used   Available Use% Mounted on cetafs-MDT0000_UUID   1462920404      501360  1364873324   0% /mnt/data[MDT:0] cetafs-OST0000_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:0] cetafs-OST0001_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:1] cetafs-OST0002_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:2] cetafs-OST0003_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:3] cetafs-OST0004_UUID   9760101272      450304  9267055468   0% /mnt/data[OST:4] cetafs-OST0005_UUID   9760101272      450304  9271366744   0% /mnt/data[OST:5] cetafs-OST0006_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:6] cetafs-OST0007_UUID   9760101272      450304  9271366744   0% /mnt/data[OST:7] cetafs-OST0008_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:8] cetafs-OST0009_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:9] cetafs-OST000a_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:10] cetafs-OST000b_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:11] cetafs-OST000c_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:12] cetafs-OST000d_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:13] cetafs-OST000e_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:14] cetafs-OST000f_UUID   9760101272       450304  9271374936   0% /mnt/data[OST:15] cetafs-OST0010_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:16] cetafs-OST0011_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:17] filesystem summary:  175681822896     8105472 166884732464   0% /mnt/data Then, I copy a 4'5GB file, but...: #> lfs getstripe CentOS-6.2-x86_64-bin-DVD1.iso CentOS-6.2-x86_64-bin-DVD1.iso lmm_stripe_count:   1 lmm_stripe_size:    262144 lmm_stripe_offset:  4     obdidx         objid        objid         group          4                 2              0x2                 0 #>  lfs df UUID                   1K-blocks        Used   Available Use% Mounted on cetafs-MDT0000_UUID   1462920404      501360  1364873324   0% /mnt/data[MDT:0] cetafs-OST0000_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:0] cetafs-OST0001_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:1] cetafs-OST0002_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:2] cetafs-OST0003_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:3] cetafs-OST0004_UUID   9760101272     4769772  9267055468   0% /mnt/data[OST:4] cetafs-OST0005_UUID   9760101272      450304  9271366744   0% /mnt/data[OST:5] cetafs-OST0006_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:6] cetafs-OST0007_UUID   9760101272      450304  9271366744   0% /mnt/data[OST:7] cetafs-OST0008_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:8] cetafs-OST0009_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:9] cetafs-OST000a_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:10] cetafs-OST000b_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:11] cetafs-OST000c_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:12] cetafs-OST000d_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:13] cetafs-OST000e_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:14] cetafs-OST000f_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:15] cetafs-OST0010_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:16] cetafs-OST0011_UUID   9760101272      450304  9271374936   0% /mnt/data[OST:17] filesystem summary:  175681822896    12424940 166880412996   0% /mnt/data The file is only allocated into OST with index 4 Can someone help me?
